I recently bought an O'Day 25, and I'm trying to track down information concerning hull construction. I removed the centerboard the other day and water started dripping out of the screw holes on the starboard side. (Centerboard pivots on a plastic/nylon pin, which sits on top of two triangular supports, which sit on top of two stainless steel plates, which are secured to the keel with two screws, each). I'm wondering what the keel is made of and what kind of damage this water might have done. How is the keel secured to the hull? Is it screwed on or is it cast in place? Would there be any wood in there that could have been affected? etc.
